Physicists have demonstrated the first “universal” programmable quantum information processor able to run any program allowed by quantum mechanics — the rules governing the submicroscopic world — using two quantum bits (qubits) of information. The processor could be a module in a future quantum computer, which theoretically could solve some important problems that are intractable [...]

Researchers have developed microscopic polymer beads that can deliver an antioxidant enzyme made naturally by the body into the heart. Injecting the enzyme-containing particles into rats’ hearts after a simulated heart attack reduced the number of dying cells and resulted in improved heart function days later.

The color vision of birds stops working considerably earlier in the course of the day than was previously believed, in fact, in the twilight. Birds need between 5 and 20 times as much light as humans to see colors.
A new study finds that heart failure patients willing to take part in clinical trials have a better prognosis than those unwilling to do so.

Whether rallying the crowd at a sporting event or participating in competition, cheerleading can be both fun and physically demanding. Although integral to cheerleading routines, performing stunts can lead to injury. Stunt-related injuries accounted for more than half (60 percent) of US cheerleading injuries from June 2006 through June 2007, according to a new study. [...]

In the quest to make hydrogen as a clean alternative fuel source, researchers have been stymied about how to create usable hydrogen that is clean and sustainable without relying on an intensive, high-energy process that outweighs the benefits of not using petroleum to power vehicles. New findings however, show that photosynthesis may function as that [...]

Researchers are reporting what is believed to be the first conclusive evidence in men that the long-term ill effects of vitamin D deficiency are amplified by lower levels of the key sex hormone estrogen, but not testosterone.

Scientists are reporting development of a nano-size capsule that boosts the body’s uptake of curcumin, an ingredient in yellow curry now being evaluated in clinical trials for treatment of several diseases.
